METHOD 0F PROVIDING CARES 0F SOAP WITH ,ADVERTISING MATTER.

Application led Hay 1, 1925, Seriall No. 27,145, and in Germany June 13,1924.

The largerportion of the pieces of soap sold is marked by means ofstamping on the exterior side of the cake or piece of soap the name ofthe manufacturer, his trade mark or the particular designation of suchsoap. This method of marking soap however shows the drawback that suchStamping 1will last a short time only, since it will soon disappear onaccount of the wearing ofi' during use, and in consequence the pieceofsoap will be void of any marking during the greater period of its use.

It has been endeavoured to. provide pieces of toilet soapl and otherswith a marking that will last during the entire period of use' and itwas proposed, for instance to introduce into transparent pieces of soapsome strips of paper provided with inscriptions and the like. It is alsoknown to embed printed labels of gelatine in transparent pieces of soap,so that thesheet of gelatine to a certain degree is covered up by thesoap while the inscription will remain visible. But this method willserve only for perma-` nently marking pieces of soap which aretransparent. Opaque pieces of soap,l as lor instance coloured andnon-transparent soaps cannot be marked visibly in accordance with theabove suggestions. For such purpose the marking must be provided on theexterior sideV of the cake or piece of soap, but on the other hand thedevice carrying such marking must be ixedly connected with the piece ofsoap to be marked. In addition said arrangement must be of sutiicientdurability during the time of using such pieceof soap, and it must notinterfere with the use of the soap.

The drawbacks referred to are overcome in that a piece of cloth orribbon, upon which the marking is printed, woven or provided otherwise,is attached to the piece or cake of soap in such a manner, that theportion of the ribbon carrying the marking will project from the pieceof soap.

A The manner of reducing this method lto practice is illustrated on theaccompanying` drawing in which Fig. 1 is a central long1. tudinalsection of a cake of soap embodying features of the-invention; Fig. 2 isa cross section thereof, and Fig. 3 is an exterior view of thecake ofsoap in its final condition.

For the purpose in question the cake or piece of soap is provided duringthe pressing step in the soap-press with a slot passing through thecentre `part of the bar of soap (see Figures 1 and 2). The said slot cmay be produced in any convenient manner, for

instance by providing the discharge opening of the press with acentrally arranged lat pike which extends almost to the ,cutting device.When cutting the band of soap ei;- truded from or otherwise leaving thepress, into the individual pieces a the latter show the slot-likelongitudinal perforation c designed to receive the section of theribbon. Before finishing the piece of soap in the tinishing press andimparting to it its final appearance or get-up, a piece of ribbon b (seeFigure 3) is introduced into the slot c of the cake or piece of soap, sothat the said ribbon will project an inch or so at one end or at bothends of the piece of soap under treatment. Subsequently the finalpressing is effected whereby thepiece of ribbon will be rmly secured .tothe piece of soap. The 7 projecting part or parts of the ribbon areprovided with the manufcturers name or trade mark or the like, so thatthe pieces ot soap thus marked still show their marking long after thestamping of the soap has disappeared. The projecting portions of theribbon may be formed into a loop or they may be lprovided with eyes orrings 1* (see Figure 3) or the like, by means of which the pieces ofsoap can be suspended.

I claim:

1. The method of providing cakes of soap with advertising devices vwhichconsistsl in forming an internal open-ended slot in said cake of soap,inserting at least one end of a flexible ribbon into said Slot andcompress-' ing .the soap to bring the opposite wallspf said slot intocontact with each other and 1nto clamping engagement with the insertedend4 of said ribbon.

2. The method of providing cakes of soap with advertising devices whichconsists in forming an internal open-ended slot in said cake of soap,placing opposite end portions of al ribbon of flexible material insurface engagement'with each other to form a ribbon-loop, inserting theengaging end portions of .said ribbon into said slot to an extent toform a ribbon loop externally of saidcake of soap, and compressing thesoap to bring the' opposite surfaces of said slot into y contact witheach other and into clamping engagement with the end portions of saidribbon. i

In testimony whereof have axed my signature.
